梅子垭水库生态因子场的分形特征
FRACTAL CHARACTER OF ECOLOGICAL FACTOR FIELD IN MEIZIYA RESERVOIR
-
摘要: 水生态系统由于多了一层水的介质以及水生生物较短的生命周期,使得其生态格局描述相对困难,对其进行定量描述的工作也相对较少。作为一个初步探索,分别应用非线性科学中的分形理论,对梅子垭水库的典型理化因子的生态因子场的水平的2维空间格局进行了分析,确定各浓度的稳定程度。Abstract: Water body is incorporated with a medium of water and the aquatic organisms have relatively short life span, and the studies on quantitative aspect of freshwater ecological patterns are relatively few. As a preliminary study, this paper deals with use of fractal theory of nonlinear science to analyze horizontal two dimension spatial pattern of concentration field of typical physicochemical factors in Meiziya Reservoir. Fractal theory is introduced in this paper for comparing and analyzing spatial occupancy potential of concentration and determining which concentration is of steady presence.
